(54) Combustor assembly with trapped vortex cavity


(57) Embodiments of the present application include a combustor assembly (25). The combustor assembly may include an annular trapped vortex cavity (116) located adjacent to a downstream end (106) of a bundle of air/fuel premixing injection tubes (102). The annular trapped vortex cavity (116) may include an opening (124) at a radially inner portion of the annular trapped vortex cavity (116) adjacent to the head end (104) of the bundle of premixing tubes (102). The annular trapped vortex cavity (116) may also include one or more air injection holes (126) and one or more fuel sources (128) disposed about the annular trapped vortex cavity (116) such that the one or more air injection holes (126) and the one or more fuel sources (128) are configured to drive a vortex (130) within the annular trapped vortex cavity (116).
